Answer:Exact Form:
4
√
5
Step-by-step explanation:
Using law of cosines:
Cos(angle) = adjacent/ hypotenuse
Cos(22) = 12/x
Rewrite to get:
X = 12/cos(22)
Simplify:
X = 12.9424
Round the answer as needed.
Answer:
The mean is 60.17 if round to the nearest hundredth.
Step-by-step explanation:
Add all the numbers together to get 361, then divide by 6 because that is how many numbers were added together.
Answer:
75 degrees
Step-by-step explanation:
I know the measure of the triangle's third angle is 75 degrees because all the angles of a triangle add up to 180 degrees. So, I did 180-62-43 and got 75. So, in order for this triangle to be true, the third triangle would have to be 75 degrees.
To check: 43 degrees+ 62 degrees+ 75 degrees = 180 degrees.
Answer:575 and 1 extra tile
Step-by-step explanation:if the total tiles is 5,176 which will be used in 9 floors .We will divide the total tiles by the floors .Therefore we will get 5176 /9 =575.111
Therefore each floor will have 575 tiles
To get the remaining tiles
575*9 = 5175 which gives us a remainder of 1 tile when you subtract the total 5176 -5175 =1
